ABSTRACT:
A molding machine for die casting, injection molding, and other similar processes, comprises a base shaped to support thereon a two-part die, and a ram for converging and diverging the die halves between open and closed positions. A pair of clamping frames are pivotally mounted on one end of the base, and include a closed border shaped to surround or receive therein side portions of the die halves. The clamping frames are laterally pivoted between a fanned-apart or open position wherein the die can be freely lifted off of the base, and a folded or closed position wherein the frame borders surround the die side portions and capture the same between the ends of the frames. In the closed position, retractable compression columns extend between the die and one end of the frames to positively lock the die halves in the closed position, whereby die separation forces developed during injection of the die are resisted substantially solely by the clamping frames.
